Objective:
This blog is to give an insight to create the NoSQL DB configuration using spring and maven.
Pre-requisite:
To create MongoDB/NoSQL configuration, following are required.
- Running MongoDB/NoSQL DB, could be protected by user name and password
- Maven dependencies
Maven Dependency
To create configuration following dependencies are required.

<properties> <java-driver.version>3.0.3</java-driver.version> <spring.version>4.1.5.RELEASE</spring.version> <spring.data.version>1.8.0.RELEASE</spring.data.version> </properties> |
Here, I chose MongoDB as NoSQL DB therefore I used mongo driver. If you want to use other NoSQL DB then add DB specific driver dependency.

Application.properties file
Add database information into this file as given below:

package config; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.mongodb.MongoDbFactory; import org.springframework.data.mongodb.config.AbstractMongoConfiguration; import org.springframework.data.mongodb.core.MongoTemplate; import org.springframework.data.mongodb.core.SimpleMongoDbFactory; import org.springframework.data.mongodb.repository.config.EnableMongoRepositories; import com.mongodb.Mongo; import com.mongodb.MongoClient; import com.mongodb.MongoClientURI; import com.uniquenotion.repository.RepositoryPackage; @Configuration @EnableMongoRepositories(basePackageClasses = RepositoryPackage.class) public class MongoConfig extends AbstractMongoConfiguration { @Value("${spring.data.mongodb.database}") private String dbName; @Value("${spring.data.mongodb.uri}") private String mongoURI; @Override protected String getDatabaseName() { return dbName; } @Bean public MongoDbFactory mongoDbFactory() throws Exception { return new SimpleMongoDbFactory(mongo(), getDatabaseName()); } @Bean public MongoTemplate mongoTemplate() throws Exception { MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory(), mappingMongoConverter()); return mongoTemplate; } @Override @Bean public Mongo mongo() throws Exception { MongoClientURI uri = new MongoClientURI(mongoURI); return new MongoClient(uri); } } |
To load all the repository classes I have added a marker interface in repository folder where all the repository present.

package com.uniquenotion.repository; public interface RepositoryPackage { } |
Now, this configuration has integrated with spring using spaing-data, mongodb driver.
If you face any difficulty to configure then leave a comment to help you out.
